HOT-WATER BOILER.

which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to water-heaters for use in heating buildings, and has for its ob-'; ject to provide a heater of simple construe-' tion and one that can be readily cleaned and "also one that affords but little lodgment for:

soot and ashes.

all of the heating-surfaces are easily kept free of soot and ashes, so that practically;

none of such heating-surface is lost.

A further and important object of the invention is ,to secure in the heater as large an amount of'water-spa'ce as possible, so that all heated surfaces may be put to the greatest use possible. V a

Another object is to surround the fire on all sides and at the top with water, so that they may be readily and easily removed and replaced, as desired. 7 In addition to these several objects certain ,detailsof construction will be described in the following specification, the advantages of "which will be readily seen. I

In the accompanying drawings, forming part of this application, Figure 1 1s a perspec- "tive view of one size of my lmproved heater.

greater heated surface for the circulating wamounting the sections of the grate, wherebyv Lratented June 19, 1906 outside section of the heater. Fig. 5 is-a horlzontal section of the heater on line X X, Fig. 2. Fig. 6 is a perspective viewof a'portion of the front water-leg, illustrating notched ledges for receiving thegrate-bar's. Fig. 7 is a perspective of portions of the sections of theheater, showing recesses for the reception of the opposite ends of the gratebars. Fig. 8 is a perspective view of a manifold for connection with all of the watersections of the heater. o 1

In the figures, A represents the base of the heater, which is merely the usual ash-receiver'below the fire-box, to be described.

Said base is provided with the'usual door B for withdrawing the ashes, and above and E resting upon thebase is a series 'of vertical A further ob ect of the invention 1s to pro-; vide a heater ofthe class described wherein.

sections 0 O and O C, the former of which are the'outside members and the latter being placed between them, as shown in Fig. 3. The form of the members C is shown Fig. 2. The top and back surfaces are at right angles to one another, and the front near the top is substantially parallel with the back surfacean'd extends downward for a short distance, where it meets the front water-leg D, to be described later. Fromthis point of meeting with'the front the said member is recessed to form the fire-space, and therefore I 7 extends backand downward in an ogee form,

substantially as shown, and thence drops vertically to the grate, the latter being illustrated in Fig. 4. Each side of the seetion is provided with'a groove or depression- E'in "front and a similar depression'F at the rear,

separated from each other for the greatest part of their length by a middle flange G, created byforming the said depressions, said flange being flush withasi'milar flange at the rear (represented by II) and one at the front J, the former forming the rear wall of the section and the latter the surface above the firespace against which the heat impinges.

The flanges II and J extend forward and downwardly and upwardly, 'res'pectively, leaving between theman openmg K for cleaning out the depressions from the front, if desired. The openings thus created between each of the sections form the holes illustrated in Fig. 3 and one of which is also shown in Fig. 1. A plate L covers the front of thesections at the top, in which holes M, one of which is shown in Fig. 2, are provided and covered by removable plates or doors The middle the figures, especially Fig. 5, the abuttingv flange G curves upward and forward, following somewhat the contour of the outer surfaces of the section and ends opposite and somewhat back from the openings K described, so that the depressions E and F communicate with one another, as shown. The former one, E, opens at E into the fire-space, as shown, and the lower end of F opens through the back of the section into a common smoke-chamber. It will thus be seen that the products of combustion must enter at the bottom of the passage E, pass upward and forward, and thence backward and downward to the bottom of F before they are liberated. Each side of each section C is thus formed, so that when two or more of them are placed side by side closed passages are created, as will be understood by reference to flanges G separating them, as described. In addition to the above, openings P andQ are made in the grooves E and F, respectively, so that circulation of heat may take place between all of the sections of which the heater may be composed, thereby insuring an even heating of all the surfaces of the entire device. The said openings P and Q are formed in the arcs of circles of different size, which, however, is immaterial; but they conform substantially with the direction in which the depressions E and F extend, as offering the least friction to the passage of the products of will show. In other respects the said outer sections are the same as the inner ones. However, as shown in Figs. 4 and 5, the said outer sections are provided with water-legs R, made integral therewith, and these constitute the sides of the fire-space, forming, in other words, part of the fire-box. The inner fire-surface of these legs are corrugated, as shown, in order to prevent warping of the leg by the intense heat and also to provide greater heat ing-surface. These sections 0 provide a solid Water-space, as shown in Fig. 5, which communicates with the water-spaces of the inner sections by pipes S and equalizer T at the tops of the sections and by means of pipes U and a manifold V beneath the sections. The latter is merely a hollow memher, with which all of the sections communicate and into each end of which are connected the pipes W, which are the returns from radiators, as will be understood.

The front water-leg D, mentioned hereinbefore, is clearly shown in Figs. 2 and 5, merely consisting of a flat box having an opening at D for the fire-door, the bottom of which rests upon the bottom member A, the top being adapted to fit the undercut recess of the sections 0, Fig. 2, it being understood that the outer sections 0 are also undercut for the same purpose, this being seen in Figs. 3 and 4, the shading in the former figure indicating the recess extending entirely across the sections, and in this figure it can be readily seen that the addition of the front D will supply the last member to completely inclose the fire-space. Though not shown, bolts or other suitable devices are employed to secure the various members together to form a complete whole, with which any dcsired packing may be used to make all joints perfectly air and gas tight. Equalizingpipes 2 and 3 connect the front D with the outer sections 7, so that free circulation of water can result.

At the bottom of the sections and between them are recesses 4 for receiving the ends of the grate-bars 5. This is clearly shown in. Figs. 2, 4, and 7, the recesses being constituted by casting a recess or notch. in each side of each section, so that when placed together an inclosure is the result, which leaves a ledge 6, upon which the ends of the said bars 5 rest. Just opposite these recesses, on the bottom of the front leg D, are cast lugs 7, each of which has a depression 8 therein, in which the opposite ends of the bars rest. By this construction the entire grate may be removed from the heater or replaced at will. In doing so the bars are reached through the firedoor, the ends of the bars at the front being raised and then withdrawn from the recesses 4 or replaced by first entering the said recesses and then dropping them into the notches in the lugs.

To my knowledge heaters have not heretofore been constructed like mine, nor do they have the advantages of my construction. By having the front water-leg separately made and removable the interior is readily reached when necessary. Further than this it will be seen that when more sections than shown in the drawings are employed a water-front of the proper size may be set in place to just fill the requirements. The peculiar tortuous passage for the smoke, in addition to the openings P and Q in said passages, give a very large area of heating-surface. While I am aware that it is not new to entirely surround the fire with water, yet the peculiar construction herein shown and described is new, coupled with the advantage of the removable front above described. I also believe it to be new to provide the means described for supporting the grate-bars and making it easy to withdraw or replace them. It will be observed that the soot maybe readily removed from the passages by inserting a brush through the front opening K or up through either of the o enings at the bottom of the passages E F. y soot or ashes lodging upon the flanges G can be easily pushed off through said opening K, and the openings P and Q, can be reached from the same opening. I have just stated that any soot lodging within the assages can be readily removed by means of a brush. As a matter of fact the places of lodgment are so little that the soot will usually readily fall either into the firespace orintothe'smoke-chamber O. This is particularly evident from a study of Fig. 2, wherein the flange Gris formed in the arc of a circle, leaving little orno place for lodgment of soot or ashes. It is well known that by havin the smoke-passages -in heaters of short length and close to the fire the soot will be kept burned off, and the draft being stronger by reason of the short passages and their close proximity to the heat aids in keeping such passages cleared. As many sections C may be em loyed as desired, these always being inclose by an outer section O and a front water-leg D of suflicient size being used to cover the whole.
